The protection of Jerusalem's holy places was also on the agenda
Palestinian Authority President Mahmoud Abbas met King Abdullah II of Jordan in Amman on Monday.
The official Palestinian news agency Wafa said the two men discussed protecting the holy places in Jerusalem after President Donald Trump's decision to recognize the city as an Israeli capital and to transfer the embassy there. American, previously installed in Tel Aviv.
According to the Jordanian news agency Petra, the two senior officials also discussed ways to restart the Israeli-Palestinian peace negotiations and the situation in the West Bank.
This was Abbas' first visit abroad since his 20 February speech to the UN Security Council.
Abbas' visit to Jordan comes as sources say his health has deteriorated in recent weeks.
The rumors, which have been denied by some senior Palestinian Authority officials, were triggered by Abbas' visit to an American hospital, where he was said to have undergone health exams, according to his aides.
While 82-year-old Abbas, a heavy smoker, has been regularly consulting doctors in the Hashemite Kingdom over the last two decades, no one could confirm whether he planned to consult again during his visit.
At Monday's meeting, Abbas praised the Jordanian monarch's support for the Palestinians and his role in defending the Islamic and Christian holy sites in Jerusalem.
Abdallah, for his part, reaffirmed his country's support for a Palestinian state and the freedom of the Palestinians.
Jordan, he said, will continue to work in coordination with other parties to resume peace talks between Palestinians and Israel on the basis of a two-state solution, the Arab Peace Initiative. 2002 and UN resolutions.
Achieving a just and comprehensive peace is the only way to end the Israeli-Palestinian conflict and achieve security and stability in the region, Abdallah told the PA leader.
Abdallah also told Abbas that Jordan is opposed to "Israeli policies, unilateral measures and recurrent attacks on holy sites in Jerusalem".
Abdallah's comments are against those of Marwan Muasher, Jordan's first ambassador to Israel and one of the architects of the Arab Peace Initiative, who said the two-state solution was no longer an option .
"Some would say that [the two-state solution] never existed, but it is certainly dead today," he told Middle East Eye, accusing Israel and the United States of the end of the process.
"Negotiations will not lead to a two-state solution today, because one of the parties does not want it - the Israeli party - and the intermediary in these talks is now totally biased towards the Israelis" said Muasher, a former foreign minister and former ambassador to the United States. "Under these conditions, we can no longer cling to an old model. "
He added that the collapse of the peace process had left Jordan in a precarious position.
"We are very vulnerable and worried about this and this explains why Jordan has always been a strong supporter of the two-state solution, as it was in Jordan's interest and not just in the interests of the Palestinians. ". "Today, it evaporated. "
